From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

if you could standardise a file format for a specific task what would you pick and why (lemmy.ml)

if you could pick a standard format for a purpose what would it be and why?

e.g. flac for lossless audio because...

(yes you can add new categories)

summary:

photos .jxl
open domain image data .exr
videos .av1
lossless audio .flac
lossy audio .opus
subtitles srt/ass
fonts .otf
container mkv (doesnt contain .jxl)
plain text utf-8 (many also say markup but disagree on the implementation)
documents .odt
archive files (this one is causing a bloodbath so i picked randomly) .tar.zst
configuration files toml
typesetting typst
interchange format .ora
models .gltf / .glb
daw session files .dawproject
otdr measurement results .xml

.opus for lossy music, .flac for lossless music, .png for image files, .mkv for video

All of them are OK, except mkv is less a file type and more a container. What should be specified is the code for video, which for most things I'd say AV1, but high res movies might not be the most suitable. Throw in opus for the audio track, and you can use mkv, but might as well use webm anyways since it's more clear what's behind it. (though can still be other things)

I'd also add that jxl should be the standard for lossy images. Better than jpg. And you want something other than png for massive images because that quickly gets costly in terms of size due to png being lossless.

Png is not always lossless. It also supports compression. But your point stands, it's not the best compression

PNG supports lossless compression through deflation, but there are encoders that can apply a lossy filter to the image to make the compression more effective.
